Quick service question

I thought i read long ago on the main page, that AT&T is or is going to, offer a 3G only plan for the iphone. Meaning you dont have to pay service for the phone.

What i want is a phone, with no phone. 3G only plan. I thought the iphone offered this, but AT&T site doesnt show it. Just the $15/month 200mB plan, but your forced to get a phone plan for another $40 a month. Is there ANY phones out there that offer JUST a 3G plan, or is it coming to the iphone sometime soon?

Don't they already complain how slow it is due to all the people on it? But even iPad users will add a large chunk because that's a 3G / WiFi only. I'd get it, but its too big for my wants. I like the size of the touch since it fits in your pocket without knowing it's there, and I'm 100% fine with tue screen size. I type a lot of my forum replys on it, such as this one
